Abstract
In this study, the syntheses and characterization of [2,3,7,8,12,13,17,18-octakis [2′-(3-quinolincarboxy)ethylhio] porphyrazinato N21N22N23N24] magnesium(II), quaternized [2,3,7,8,12,13,17,18-octakis [2′-(3-quinolincarboxy)ethylhio] porpyrazinato N21N22N23N24] magnesium(II), [2,3,7,8,12,13,17,18-octakis[2′-(3-quinolinecarboxy)-ethylthio]21H23H N21N22N23N24 porphyrazine and [2,3,7,8,12,13,17,18-octakis[2′-(3-quinolinecarboxy)-ethylthio]porphyrazinato N21N22N23N24} zinc are described. The new compounds have been characterized by elemental analysis, FT-IR, 1H-NMR, and mass spectra. General trends are described for fluorescence quantum yields of these compounds in dimethylsulfoxide (DMSO). In this study, the effects quaternization of the substituents on the photophysical and spectroscopic properties are also reported.
